Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To make the direction of a permanent magnet and the rotational speed of a synchronous motor estimatable even under a wide range of conditions by estimating the direction of the magnet and correcting the estimated rotational speed of the motor by means of a position and speed estimating means. SOLUTION: A speed estimating means 20 incorporated in a position and speed estimating means 10 estimates the rotational speed ωm1 of a synchronous motor by inputting a d-axis current id, a q-axis current iq, and a q-axis voltage vg and a positional error estimating means 21 outputs the error in the estimated direction θg of a permanent magnet. Then a speed error estimating device 22 outputs the rotational speed error corresponding to the error in the direction θg of the permanent magnet and an adder 23 calculates the sum of the output of the speed error estimating device 22 and the output gh of a speed error detector and outputs the sum ωm2 of the rotational speed errors corresponding to the errors in the direction θg of the permanent magnet.  In addition, another adder 26 outputs the sum ωmx of the output ÷m1 of the speed estimating means 20 and the output ωm2 of the adder 23 and an integrator 27 integrates the sum ωmx. Then the position and speed estimating means 10 outputs the integrated result as the direction θg. Therefore, the rotational speed of a synchronous motor and the direction of the permanent magnet can be estimated.

Title: Optical signal bypass designating system
Inventor: NISHITO KATSUHIKO
IPC: H04B10/038
Filed: 1989-09-21
Abstract: PURPOSE:To apply a bypass and to attain the segmentation of a fault even when the fault occurs in a large scale circuit requiring high speed operation by superposing an optical signal bypass designation from a central station to a terminal station on a power source line for an optical signal bypass, applying the bypass and the releasing of the optical signal. CONSTITUTION:When a central station designates the bypass to a terminal station, the central station sends a bypass command signal while superimposing the signal on the signal of an optical signal bypass power line 2a. The bypass designation/releasing control section 8A of the terminal station extracts and decode the superimposed bypass designating signal to select and control the bypass to a selector 7. The bypass is released similarly. Since the control of bypass is implemented not through a loop control section 6 composed of a high speed large scale circuit, the bypass designation from the center station through the bypass designation/releasing control section 8A is attained even when the fault of the loop control section 6 takes place. Thus, system-down is prevented.

IPC: E21B17/02
Filed: 1994-10-13
Abstract: PURPOSE:To properly grasp the lock condition of a rod by simplifying the structure of a rod coupling device and indicating the lock condition with an electrical signal from a sensor. CONSTITUTION:The projected sections 15a and 15b of a lock ring 15 come in contact with the rear ends 14a and 14a of lock members 14 and 14, and the forward ends of the members 14 and 14 are thereby projected into a joint hole 13a for engagement with the lock grooves 12b and 12b of a male joint 12a. Thus, the lock members 14 and 14 are kept in locked state. In this case, a sensor 21 fitted to the cover 24 of a lock engagement and disengagement ring 18 detects the approach of a disc 20 at a shorter distance and sends an electric signal for the locked state to a drive circuit 28 for a lamp or the like on the control panel 27 of a crawler travel body, thereby turning off the indicator lamp 29 of a rod connection device 10 and an indicator lamp 35 on the operation panel 34 of a driver's cab 33. At the same time, an alarm unit 36 on the panel 34 of the cab 33 is made to stop. As a result, a worker on the ground and an operator can independently grasp the locked state, while the former visually confirming the state of the lamp 29 and the latter watching the indicator lamp 35 and the alarm unit 36 in the cab.

Title: Motor operated vehicle
Inventor: NAKAJIMA MOTOHIRO
IPC: B60L7/00
Filed: 1992-09-17
Abstract: PURPOSE:To stop a motor even at the time of erroneously operating a CPU, etc., by altering an output torque command value to a value for stopping the motor and controlling a motor current when an output torque cut command is received. CONSTITUTION:When a driver selects a neutral range or a parking range to instruct cut-off of an output torque, output torque cut-off instructing means (TC) 32 generates an output torque cut-off command signal (CS) (a). When the CSa is input to output torque command value calculating means (OT) 15, the OT 15 sets the output torque command value to zero or close to zero to stop a motor 25. A motor driving circuit 34, when receiving the output torque command value, stops the supply of a motor current to the motor 25. The CSa is output to a current interrupting mechanism 36 through a signal delay circuit 35 without intermediary of a CPU. Accordingly, even if the OT 15, the motor circuit 35 are erroneously operated, the motor 25 can be effectively stopped with the CSa.
